Title: Improvements in or relating to telegraph signalling systems
Inventor: O'ROURKE PETER JOHN
IPC: H04J3/07
Filed: 1968-01-22
Abstract: 1,206,714. Digital transmission systems; multiplex pulse code signalling. PLESSEY TELECOMMUNICATIONS RESEARCH Ltd. 14 Jan., 1969 [22 Jan., 1968], No. 3299/68. Headings H4L and H4P. In a digital transmission system in which signals are transmitted at a rate greater than the rate of the data at the transmitter input, groups of "fill" digits are added to the data prior to transmission. The signals are sent in blocks comprising a number of data and fill groups. The number of fill digits in the last group of a block varies, and this number is indicated by the code combination of a preceding fill group. At the transmitter, input binary data at a speed which may vary is transmitted over a higher speed sub-channel of a multiplex channel. The serial input data passes via a buffer and regenerator to a unit comprising a store from which it passes to a data register. A counter is incremented whenever a bit is placed in and is decremented whenever a bit is read from, the data register, so that the counter shows the number of bits in the data register which have yet to be transmitted. The cell in the data register from which the data is read out is selected in dependence upon the content of the counter. Under the control of a unit fed by clock pulses at the transmitted bit rate, readout from the data register is stopped periodically for the transmission of a fill group. Each block of signals starts with a synchronizing fill group. The last fill group in a block has a nominal length which is increased or decreased by one bit in dependence upon whether the counter content lies below a certain value or exceeds another value at the end of the preceding data block. An intermediate fill group in the current block shows by its element combination the number of bits in the last fill group of this block. At the receiver the fill groups are removed from the received block, the data groups passing to a register associated with a counter similar to that at the transmitter and which feeds a unit which selects from which cell read-out shall take place. If the counter content exceeds or falls below certain values the rate of read-out from the register is increased or decreased, readout being at a lower rate than write-in to the register.

Abstract: Furfuryl alcohol containing a polymerization catalyst is used as carbonisable binder in admixture with powdered carbon to form a graphite body or as a carbonisable impregnant to increase the density of a preformed graphite body.  The furfuryl alcohol may be used first to form a graphite article and then to increase its density.  The catalyst may be maleic anhydride, sulphamic acid, nitric acid, oxalic acid, sodium, potassium or cupric nitrate, or uranyl nitrate hexahydrate.  The latter catalyst produces a "loaded" article for use in nuclear reactors.  UO2, U3O8, or UO3\t may be incorporated in the graphitisable mixture to produce a uranium loading of up to 1.5 gm./c.c.  The carbon may be in the form of raw or calcined coke or graphite flour or furnace, thermal, or lamp black.  The coke or graphite may have been formed from furfuryl alcohol.  The graphitisable mixture may be extruded or pressed to form a shaped "green" body.  In the former case the mixture may contain methyl cellulose.  The green body may be of laminar construction, at least one layer being loaded.  The green body may be graphitised entirely under pressure or up to the end of the curing step only. The graphite article may have an apparent density of 1.28-1.57 gm./c.c. and a fibre stress of 2780-3200 p.s.i.  Examples are given.

Abstract: 879,094. Free piston compressors. MAREP, S. N., OLLIER, J. G. H., and GROSSHANS, G. F. Feb. 5, 1960 [Feb. 6, 1959], No. 4185/60. Class 7(2). [Also in Group XXVIII] A diesel motor for actuating compressor pistons 7, 7<SP>1</SP> (see Group XXVIII), comprises opposed pistons 5, 5<SP>1</SP> within a cylinder 1 enclosed by a casing 2, scavenging pistons 6, 6<SP>1</SP> carried by the outer ends of pistons 5, 51 and connected totogether by synchronizing racks 9, 9<SP>1</SP> and a pinion 10 and to the compressor pistons by rods 8, 81; the cylinder 1 having scavenging air ports 3 and air inlet ports 21, 21<SP>1</SP> through which air is forced by the pistons 6, 61 during their inward strokes effected by a cushion of compressed air in each of spaces 20, 201, a fuel injection device 18 and exhaust ports 4. To start up the motor, spaces 20, 201 are connected by a duct 26 to a compressed air supply 42 and during normal working cushion pressure is regulated by a known device 22 comprising a three-headed spring-biased vertical slide valve 23 having the space 24 between the upper and middle head connected by ducts 26 to the cushioning spaces 20, 20<SP>1</SP>, the space 22b between the middle and lowermost head being connected by a duct 27 and a one-way valve 28 to the casing 2 and the lowermost face 22d of the bottom head being vented to atmosphere. In operation an increased piston stroke results in an increased cushion pressure which lifts the valve 23 against a spring 25 and connects ducts 26, 26a to atmosphere until equilibrium is reached. Conversely, a decreased piston stroke results in a decreased cushion pressure which allows the valve 23 to descend and scavenging air to pass from duct 27 to duct 26 and hence to spaces 20, 201.
